VENTILATQB.

Specification of Letters Patent.

Patented. Sept. 21, 11909.

Application led' March 18, 1909. Serial No. 484,386.

ToV all whom 'it may concern:

Be it known that I, CHARLES A.PETERsoN,

a citizen of the United States, and a resident of the city of Chicago,count-y of Cook, and State of Illinois, have invented certain new anduseful Improvements in Ventilators, of which the following is aspecification.

. My invention relates to improvements lin ventilators, and moreparticularly to aventilator adapted to be inserted in the Walls of abuilding, the object being to provide a dei vice of this character thatshall be neat in appearance andeficient in operation.

A further object of my invention is to provide al ventilator that may beeasily removed from its place in the wall for cleansing purposes, and afurther object is to provide suitable fastening devices to holdthe'ventilator in position. And a still further object is to providesuitable hinged lids for closing the ventilator openings.

Other objects will appear hereinafter. i

lith t-hese objects in view my invention consists in the novelconstruction and arrangement of parts all. as will be hereinafter fullydescribed and particularly pointed'out inthe appended claims.

My invention will be more readily understood by reference to theaccompanying drawings forming tion, and in which,

Figure 1 is a central vertical section showing my improved ventilator inits preferred form, and Fig. 2 is a section thereof taken on the line a:of Fig. 1 showing a hinged lid in elevation.

Referring now to the drawings 1 designates the wall of the building and2 the removable rectangular ventilator inserted therein. The ventilator2 comprises a central member 2,` a top member 3 and a bottom member 4.The central member 2 consists of a horizontal partition 5 havingintegral rectangular deflectors 6 and 6 eX- tending upwardly anddownwardly therefrom respectively and disposed perpendicular thereto.The top member 3 consists of a rectangular top portion T coextensive andparallel with the partition 5 having integral rectangular deflectors 8extending downa part of this specificawardly therefrom and disposedperpendicu! lar thereto, and the bottom member 4 consists of arectangular bottomvportion 9 coextensive and parallel with the partition5 having integral rectangular delectors 10 ex- Itending upwardlytherefrom and disposed perpendicular thereto, all of said deflectors`being equally spaced. The deflectors 8 are arranged in the same planesas the deflectors y6 of the partition 5, and the deflectors 10 in thesame'planes as the deiectors 6 of said partition, the detlectors 8 and1() having edges which are parallel with said partition 1 and spaced ata dista-nce therefrom, and the deflectors 6 and 6 having edges alsoparallel with said partition and spaced at a distance from the portions7 and 9 respectively. The end portions 11 are integral with the partition 5 and the deflectors 6 and 6', as shown in Fig. 2, lthe top andbottom edges thereof being adapted to abut the portions 7 and 9respectively.

n The ventilator is adapted to it inthe rectangular opening in the wall1, and when the same is removed the'members 2, 3 and 4f may be easilyseparated' for cleansing'purposes.

When the ventilator is in position in the wall 1 and the lids 12 are inthe open position, air may circulate freely in a sinuous course asindicated by arrows in Fig. 1, but when said lids are closed aircirculation isprevented. The stops 13 are rectangular blocks project--ing over the wall opening and secured to the wall 1 on the outsidethereof. These stops prevent the ventilator from moving in one directionand the button 13 pivoted to the wall 1 prevents movement in the other.

To prevent snow or rain from entering the ventilator the openings on theoutslde thereof are formed adjacent the center and lower edge, itbeingobvious that if the outside openings were arranged adjacent the centerand-top edge as on the inside of the ventilator rain would readilycollect and render the `ventilator ineffectual.

The lids 12 are substantially rectangular in form and are hinged to thebrackets 14 secured to the wall 1, the handles 15 being oentrallydisposed on the lids in order that the same may be easily opened orclosed. And a handle 16 is secured to the inside of the ventilator, bymeans of which the same may be easily withdrawn.

While I have shown what I deem to be the preferable form of my improvedVentilator, I do not wish to be limited thereto, as there might beslight modifications thereof which would be comprehended within thescope of my invention.

Having described my invention what I claim as new desire to secure byLetters l staggered de lectors 6 and 6", and side Walls Patent is:

1. A device of the class described, comprising a horizontal partitionprovided with integral upwardly and downwardly extending staggereddelectors and side walls integral with said partition and deiiectors andslightly longer than the deflectors, and upper and lower plates providedwith deflectors adapted to extend into the space between said firstmentioned defiectors, substantially as described.

2. The combination witha wall 1 having a rectangular opening, with arectangular ventilator comprising the horizontal partition 5,

11 all cast integral wit-h each other; plates v7 and 9 provided withdelectors 8 and 10; hinged lids l12 for closing the openings throughsaid ventilators; and means for removably locking said ventilator insaid open- En testimony whereof yI have signed my name to thisspecification in the presence of two subscribing witnesses.
